The next day, Chen Chong was awakened by the phone ringing.

"Hello?"

"Mr. Chen? Are you at home?" A loud voice came from the phone and asked in a row, "Is there a buyer who wants to see the house. Is it convenient now?"

"Okay, bring it here."

He put down the phone, turned over and sat up, feeling dry mouth and dizzy.

It’s not a hangover. I didn’t drink a few sips of wine last night. I mainly didn’t sleep well. I first drew the design drawing until midnight. After lying on the bed, my mind was like boiling hot water, and I was flipping with all kinds of strange thoughts. There was no way, who made the information I obtained yesterday have a bit of a large amount... I tossed and turned and couldn’t sleep until dawn, and I fell asleep half-wake up.

My psychological quality is not good... It seems that it is important to learn from Li Kaiyuan more and maintain a good mood.

Thinking more is heartbreaking. As the scope of communication expands, you may encounter ten or eight messages containing great opportunities every day. If you do it every time like last night, you will be nervous after three months and die in three years.

Looking at the time, it was already past ten o'clock, Chen Chong took a quick shower, cleared his mind, then walked into the study, packed up the letters and drawings that had not been sent yet, and then heard a knock on the door.

There are three buyers who view the house, a young couple, who has a mother-in-law outside, and the standard configuration for buying a house.

"Hey, look, this apartment is so good. Look here, the kitchen is clean and there is no smoke on the walls. It's the same as the new house, and here, look, you can see Fu Ren Street from here, it's just right, it's convenient to buy things, and it's not noisy..."

Chen Chong let them in, stood aside, and let the agent take the buyer to visit, and introduced them in a vague way.

After a while, the man also came over and took out a pack of cigarettes.

"Thank you, I won't smoke." In my previous life, I was full of smoking and drinking, but after traveling through time, I seemed to have lost my smoking addiction and just quit.

"This house is pretty good." The man was wearing glasses and was gentle. He put away his cigarette and asked, "Why do you want to sell it?"

"My parents passed away, I still have to go to school." Chen Chong took out the excuse he had prepared long ago, "Hong Kong University, the tuition fee is too expensive, it's not OK to sell it."

"A top student from the University of Hong Kong." The man expressed his envy and admiration - the University of Hong Kong is a product of British colonial policy. Most of the senior staff of the Hong Kong government graduated from the University of Hong Kong. They are known as civil servant training bases and have a special status in the hearts of Hong Kong people.

"Sorry, I'll ask." The man in glasses hesitated for a moment and asked again: "How did you... your parents die?"

"I was hit in Causeway Bay by car accident." Chen Chong explained that buying a second-hand house is very taboo to have any misfortunes at home, which is understandable.

"Oh." The man in glasses seemed not very good at speaking. After holding it in for a while, he said "Sadness and reconciliation", and then walked back and whispered a few words to his wife and mother-in-law.

After a while, the man in glasses came over again. Chen Chong felt that there was a chance - buying a house with a woman is more uncomfortable than shopping with a woman. Judging from his relaxed look, he probably had two women satisfied with the house.

"My name is Wen Renjie." The man in glasses introduced himself.

"Chen Chong." He shook his hands casually, and Chen Chong said, "The surname Wen Ren is quite rare."

"You are the first to know that my surname is Wenren, and others think that my surname is Wen." The man in glasses was surprised at first, and soon felt relieved. "There are so many books in the study and the family background. Are your parents all intellectuals?"

"That's right." Chen Chong smiled. He was actually playing web games. He knew this duplicate name when he randomly took a name...

Chen Chong and Wen Renjie were chatting, but they didn't notice a loli flashing at the door.

The house is not big, with a total of only 78 square meters. The two women walked around three or four times and were optimistic, so they sat down to negotiate the price.

After a while of argument, Chen Chong agreed to give away all the furniture and appliances, he finalized the transaction price of 450,000 yuan, signed the agreement, and made an appointment for the transfer of the house. As for other complicated processes, his own agency helped him to handle it.

As soon as the buyer left, Li Kaiyuan came to the door. Her face turned red and slightly short of breath. It was obvious that she was rushing to come after hearing the news, and a small tail was followed by.

As soon as they met, she asked loudly: "A Chong, what are you doing for selling a house?"

Before Chen Chong could explain, she said in a row: "If you are short of money, you can tell me. Although my family is not rich, there is always money to support you in school. How can you sell the house left by your parents!"

Chen Chong was moved in his heart, and Li Kaiyuan was really good to him.

"Sister Yuanyuan, you misunderstood. I didn't sell my house because I lacked money in school."

"What's that for?"

Chen Chong greeted Li Kaiyuan to walk into the study, took out the design drawings he drew last night, and said, "This is the toy drawing I designed. Sister Yuanyuan, you are an expert, help me see how much it costs to make this?"

"The toys you designed?" Li Kaiyuan casually glanced at the drawings and asked with a frown: "You sold the house and went to the toy business?"

"yes."

"Nonnao, you are a nerd, what business is it for?" Li Kaiyuan roared loudly, and Li Tianbao grimaced at Chen Chong - the first time my sister taught her brother Chong so loudly.

"Isn't this there you, Sister Yuanyuan?" Chen Chong said with a slutty smile: "Sister Yuanyuan, don't you want to resign? You should resign and do this toy business with me."

"You are really obsessed with it." Li Kaiyuan was so angry that he couldn't cry and said powerlessly: "I haven't resigned yet."

"Don't quit, Aunt Liu, I'll go and tell you." Chen Chong looked indifferent, "Help me see how much it costs to do this."

Seeing that Chen Chong was serious about what he said, Li Kaiyuan had no choice but to pick up the drawings, looked carefully, and asked Chen Chong a few questions, and then calculated for a while, saying: "The materials are not worth much money. ABS plastic is very cheap, mainly due to labor costs. Your toy has a somewhat complicated structure and needs to be assembled manually."

"Then how much do you estimate the cost?"

"The material cost is very low, about two yuan." Li Kaiyuan looked down on Chen Chong angrily, "The key is labor cost. I have never done this thing before. Who knows how much time it takes to assemble one and how to calculate the cost? He is really a nerd, and it is not a business cause at all!"

Chen Chong touched his nose and smiled awkwardly, a little anxious, and was so embarrassing.

"Brother Chong, what is this toy called?" Li Tianbao lay on the chair, looking at the design drawings over and over again, "It looks so complicated and should be fun."

"This is called a magic cube, a magic cube, abbreviated as a magic cube."

"Rude's Cube?" Li Kaiyuan stared at Chen Chong and dissuaded: "The name is weird. A Chong, why do you want to do this? Business is not easy to do now, and there is a great risk."

"Sister Yuanyuan, if I tell you that this toy contains a lot of mathematical knowledge, can exercise the brain, improve intelligence, develop imagination, and exercise memory. It is simple and easy to use, very fun, can combine education and entertainment, and has many benefits for children's growth. The price is not expensive, would you buy one for Tianbao?"

"If there is such a toy, of course I will buy it." Li Kaiyuan did not hesitate and asked back, "It's so vague. Is your Rubik's Cube so magical?"

"Of course!" Chen Chong answered with confidence and confidence.

Of course I am confident!

The Rubik's Cube can withstand the test of time. Since its invention, it has been popular all over the world for more than 30 years and is well-selling and is recognized as the best educational toy.

In my previous life, Chen Chong had a special puzzle for a while. In order to quickly twist it, he checked a lot of information. When he graduated from college, his thesis was about the Rubik's Cube, and he knew it well.

There are different types of Rubik's Cubes, Level 2 Rubik's Cubes, Level 3 Rubik's Cubes, Level 4 Rubik's Cubes, Level 5 Rubik's Cubes, etc. Among them, the second-level Rubik's Cubes appeared very early, but they are too simple and not popular.

In 1974, Professor Rubik Elne from the School of Architecture, Budapest, Hungary, invented the third-order Rubik's Cube in order to help students understand the composition and structure of space cubes.

The first batch of third-order Rubik's Cubes were sold in toy stores in Budapest in 1977. Due to the Cold War, the Western world knew nothing about it. In 1978, at an international mathematician representative meeting held in Helsinki, the capital of Finland, Hungarian mathematicians introduced the Rubik's Cube to the experts and scholars at the meeting. Only a few people in the Western world knew about the existence of this toy, but it did not attract widespread attention.

In 1979, the boss of a British toy company went on a business trip to Hungary and discovered a third-level Rubik cube, which was like a treasure. So he cooperated with Rubik and took Rubik to participate in the International Toy Expo held in early 1980, which caused a sensation. Rubik's Cube quickly became popular all over the world. In just two years, more than 2 million genuine Rubik's Cubes were sold, and the number of pirated versions was several times that of genuine versions. By the mid-1980s, nearly 1 billion people around the world had played Rubik's Cubes.

The Rubik's Cube is cheap and has low requirements for start-up capital. As long as it is operated properly, it will soon sweep the world and bring a lot of money. It is an excellent choice to dig the first pot of gold.

What's even better is that Rubik only applied for domestic Hungary patents, but did not apply for international patents. In 1979, the Rubik's Cube had already passed the international patent protection period and produced the Rubik's Cube, and there was no patent problem at all.

What Chen Chong is doing now is to compete with the British toy company for a time difference and take the market advantage before they discover the Rubik's Cube.

Chen Chong remembered that the British toy company was extremely shameless. After discovering the Rubik's Cube, in order to take advantage of the law, he tried every means to take advantage of the law and applied for "Rubik's Cube copyright" to Professor Rubik. Toys are not virtual products such as papers and novels, so how can there be copyright?

But the ridiculous thing is that the toy company succeeded.

Since then, the third-level Rubik's Cube has become Rubik's exclusive business. He is the only one in the world who can produce third-level Rubik's Cubes. In the later generations, even if the structure is different from Rubik's, it is legally considered a copycat that infringes on Rubik's "copyright"...

If Shen Chong took the lead in occupying the Rubik's Cube market and cut off the path of that greedy British company from the root, there should be no "Rubik's Cube copyright" again, which will benefit the future of Rubik's Cube enthusiasts.

Moreover, the speed of information dissemination in this era is limited, and it is covered by the Cold War iron curtain. When Rubik discovered Shen Chong's Rubik's Cube and wanted to find fault, Shen Chong had already made a fortune. Even if he found fault, Shen Chong was not afraid. The design drawings of the Rubik's Cube were improved by many masters in later generations. The structure was stronger and the sliding was smoother. It was not the same as Rubik's third-level Rubik's Rubik's structure. It was not worth competing with Rubik in the market.

"Brave!"

Chen Chong's confidence seemed to be unconvincing. Li Tianbao gave him a big roll of his eyes without hesitation, while Li Kaiyuan's eyes flashed and thoughtful.

"Little girl... can make trouble." Chen Chong rubbed Li Tianbao's head, pondered slightly, and said, "The drawings look unconvincing. Let's do this, is Uncle Li at home? Find him to use wood to make a sample, and you will know what I said is true."

"Okay." Li Kaiyuan stood up, rolled up the drawings, and said, "Let's go, go to Yindu Theater to find my dad now."
